Used DNS / DAINIPPON / SCREEN AS 2000 #9382445 for sale

DNS / DAINIPPON / SCREEN AS 2000 is a wafer grinding, lapping and polishing equipment that was designed by the Japanese company DNS. The system is capable of producing ultra-smooth finishes on a variety of substrates including sapphire and various other materials. The unit employs a combination of precise motion control, precise air pressure and dedicated abrasive delivery methods to achieve the highest level of smoothness. The machine features a high frequency ultrasonic transducer, which enables superior grinding and lapping performance over a wide range of materials. Additionally, the high frequency transducer also eliminates the need for additional lapping steps. DNS AS 2000 features a modular axes design in which all of the axes of motion are interlinked and work simultaneously for improved precision and accuracy. The total number of axes in the tool include three grinding, two lapping and one polishing axis. It is powered by a servo motor and a variety of sensors including a force sensor, zeta background sensor and a tool holder sensor. The force sensor is used to measure the forces applied on the workpiece while the zeta background sensor measures the background temperature of the area surrounding the asset. The tool holder sensor monitors the tool holder motion relative to the workpiece. The model is capable of processing substrates up to 12" (304.8 mm) in diameter and 8" (203.2 mm) in thickness. The grinding speed for SCREEN AS-2000 is up to 50 m/s and the typical lapping speed is between 0 - 2000 m/min. The equipment is capable of adjustable grinding and lapping pressure, with the latter being adjustable from 0.5-10 bar. The pneumatic system also provides lapping profiles with multiple modes such as time control and grinding time. AS 2000 is supplied with a manual console from which the grinding, lapping and polishing parameters can be defined. Additionally, the input and output interfaces are also provided for convenient access and easy control of the unit. DAINIPPON AS 2000 is also equipped with a sophisticated microprocessor control unit to ensure precise control and smooth operations. Overall, SCREEN AS 2000 is an advanced wafer grinding, lapping and polishing machine that is capable of producing ultra-smooth finishes with high accuracy. The tool is supplied with a manual console and interface to enable easy operation and monitoring of the parameters, as well as provides multiple modes and adjustable grinding and lapping pressures.
